Three-dimensional stranding, untwisting and cabling machine for large-length great-section high-voltage photoelectric composite submarine cable

Abstract

The invention discloses a three-dimensional stranding, untwisting and cabling machine for a large-length great-section high-voltage photoelectric composite submarine cable, which comprises a stranding rotating plate and a mechanical untwisting device of a supporting plate on the stranding rotating plate, the rotation of the stranding rotating plate is transmitted to the supporting plate through gears, and the supporting plate rotates by means of a mechanical swing bearing. The cabling machine also comprises a variable frequency motor, a PLC (Programmable Logic Controller) control system and an electrical untwisting device of an untwisting system, wherein the PLC control system controls the variable frequency motor to drive the supporting plate to rotate, the untwisting system is arranged above the supporting plate and detects the cable, the detection data is fed back to the PLC control system, the PLC control system compares the detection data with the set untwisting rate, the actual untwisting rate is obtained through comparison, and the deviation value is calculation so as to perform closed loop regulation to the variable frequency motor. The sufficient untwisting of each supporting plate untwisting device before cabling is realized through mechanical untwisting and electrical untwisting.

Description

technical field [0001] The invention relates to a cable forming machine, in particular to a cable forming machine with a large length and a large cross-section and a high-voltage photoelectric composite submarine cable. Background technique [0002] As described in the Chinese patent with the authorized announcement number CN201946388U, the number of pay-off reels of the vertical cable forming machine used by submarine cable manufacturers is generally six reels, and at most six core wires can be twisted back into cables. Among them, there are three smaller core wires that use the wire reel to pay out the wires. The core wires are installed in the wire reel. Tray-type pay-off, the core wires are directly stacked on the untwisted tray, this kind of tray-type pay-off is called single-tray passive pay-off. All untwist trays are supported on the twisting turntable. During operation, the twisting action of the core wire is realized by the rotation of the twisting turntable, and ...

AI Technical Summary

Problems solved by technology

[0005] However, when mechanically untwisting, this cable forming machine cannot solve its own torsion force generated during movement, and cannot fully untwist, and it cannot avoid torsion damage caused by the failure of the equipment itself
